I'm hitting this warning a lot in my pants runs, and I suspect it's slowing down execution times:

15:52:47.86 [WARN] Completed: Find Python interpreter to bootstrap PEX - No bootstrap Python executable could be found from the option `interpreter_search_paths` in the `[python-setup]` scope. Will attempt to run PEXes directly.

My config looks like this:

[python-setup]
interpreter_search_paths = ["/usr/bin/python3"]

What's wrong with this search path? That Python definitely exists. What could make it invalid?

What version of Pants?

2.7.1rc1

https://github.com/pantsbuild/pants/pull/13278 is in 2.9.x which is almost 2.9.0 but not quite: https://pypi.org/project/pantsbuild.pants/2.9.0rc5/

ah oh yeah

Excellent. Thank you.
